Abstract

ABSTRACT This study aims to explore the relationship between the traditional musical instrument of the Toba Batak tribe known as Tagading and the concept of geometry. This study uses a qualitative approach through direct observation, interviews, and documentation to collect relevant data. The results of the study show that Tagading has geometric concepts in the form of geometric shapes and geometric shapes. The shape of the circle, as well as the structure and placement of the wood in Tagading illustrate these geometric concepts. Apart from that, the rhythmic patterns and long proportions of wood in Tagading also illustrate the relationship between music and mathematics. This research has important implications in developing mathematics learning methods that are relevant to local culture, as well as providing innovative learning experiences for students. The findings of this study can enrich our understanding of the relationship between culture, traditional music and geometric concepts.

Abstract

Education and Culture are things that cannot be separated. Mathematical concepts are sometimes embedded naturally in people's culture. Mathematics with cultural nuances (ethnomathematics) can have a big influence on mathematics learning. This research aims to examine the use of ethnomathematics in Humbang Batik motifs in Transformational Geometry material. Research data was obtained by literature study, observation, interviews and documentation. Interviews were conducted with two Humbang batik craftsmen. This research is included in the type of exploratory research, namely exploring the form of Humbang batik motifs which can be utilized in the transformation geometry learning process. The approach used in this research is an ethnographic approach which aims to obtain an in-depth description and analysis of culture based on field research. The ethnomathematics in Humbang batik are reflection, translation, rotation and dilation in transformation geometry, which is found in Humbang Batik motifs such as coffee motifs, Sisingamangaraja swords, Gorga Simeol Meol, Sanduduk flowers, and others.
